Why no height/weight input? Unlike per-kg supplements (creatine, protein), Methylene Blue has no published bodyweight-adjusted dosing in the research behind it. This calculator doesn't fabricate a per-kg formula that doesn't exist in the literature.

The manufacturer’s own guidance for this product is to start with one capsule in the morning to assess tolerance, which is the only dose option offered here. Methylene blue has real, serious interactions — particularly with SSRIs and other serotonergic medications, where it carries an MAOI-like risk of serotonin syndrome — and the manufacturer’s own dosing notes reference a bodyweight-scaled range (roughly 0.3–4.0 mg/kg). We’re not building that bodyweight math into this calculator: this is one supplement on our network where dose decisions genuinely belong in a conversation with a doctor, not a calculator output.
A randomized, double-blind, placebo-controlled human trial using functional MRI found that a single 280 mg oral dose of USP-grade methylene blue (roughly 4 mg/kg, more than 20 times this product’s capsule dose) improved measures of sustained attention and short-term memory an hour after administration [1]. That trial studied a single acute high dose in a research setting, not routine daily use of a 12 mg capsule — it’s cited as context for methylene blue’s cognitive research generally, not evidence for daily use at this product’s dose.
If you’re on any prescription medication, especially antidepressants, talk to your doctor before starting this product — this is not boilerplate advice for methylene blue specifically.
